I like this idea. However, as performance is still somewhat of an issue (and 
perl5, at least, eats immense amounts of memory even in C), I would propose 
that the intermediate language (and that of the microperl6) be C, rather 
than something higher level with more overhead.

However, perl6 can't be *exclusively* in perl5. After all, there will be 
some code modules (scalar variable handling, for instance) that are not 
optional. Even if they're wrapped in a perl5 script, the script likely won't 
be much more than a bunch of here-docs, with maybe a few conditionals 
depending on the configuration chosen... ;)
